HAIR-CRIMPER.

SPECIFICATION forming part of Letters Patent No. 710,702, dated October'7, 1902.

Application filed June 28, 1902. Serial No. 113,297. (No model.)

To all w/tont it may concern:

Beit known that I, JAMES F. MARTIN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, haveinvented a certain new and useful Hair-Crimper, ofwhich the follow ing is a specification.

My invention relates to that class of haircrimpers in which two or morejaws are secured together at one of their ends in such manner as to bemovable with reference to each other; and the principal objects are toprovide suitable means for connecting the jaws, whereby the veXatiouspulling or catching of the hair will be wholly avoided, and to provide aquick and efficient interlock for the free ends of the jaws which willbe positive against accidental movement of the jaws in all directions.The objects thus stated, the invention comprises the improvementshereinafter described and claimed.

The nature, characteristic features, and scope of the invention will bemore fully understood from the following description,taken in connectionwith the accompanying drawings, forming part hereof, and in which-Figure 1 is a perspective view of a haircrimper embodying features ofthe invention, showing the same in closed position. Fig. 2 is alongitudinal sectional View of the same. Fig. 3 is a similar view withhair applied to the crimper, illustrating how the jaws are positivelylocked against accidental movement in all directions; and Fig. 4 is aview illustrating the crimper in open position.

In the drawings, 1 and 2 are jaws or strips connected together at one oftheir ends, so as to be movablein respect to each other, and for thispurpose use is made of the hinge or eyelet 3, because it does not catchor pull the hair, as does the usual pivot-pin or rivet, and is far moreattractive looking, not to mention the fact that it exerts less frictionon the parts and that consequently there is much 45 less wear. Thesejaws or strips may be made of any appropriate material, as metal,celluloid, or any variety of materials too numerous to mention, and, ifdesirable, they may be covered with fabric or the like. One of the jawshas its free end served with an overhanging projection or lip 4., whichforms a part of or may be applied thereto, and said projection or lip isprovided with a somewhatelongated concavity or depression 5, adapted toengage with a complemental projection or 5 5 hump 6 on the free end ofthe other jaw, and said parts constitute a simple and efficientinterlock for securing the jaws in their closed position. The jaws arenot only locked against accidental lateral movement, but are, asgraphically shown in Fig. 3, locked against accidental movement in alldirections. In use these jaws or strips are opened in respect to eachother and a strand or strands of hair is or are wound around and betweenthem. They are then closed in respect to each other by causing the parts5 and 6 to interlock and serve to keep the hair in position until itbecomes crimped. Of course the catch or interlock may be differently orelsewhere 10- 7o cated than as statedfor instance, by forming orapplying its respective parts to the sides of the jaws 1 and 2 insteadof at their ends.

It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in details without departing fromthe spirit thereof. Hence I do not limit myself to the preciseconstruction and arrangement of parts hereinabove set forth andillustrated in the acompanying drawings; but,

Having thus described the nature and objects of the invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. A hair-crimper comprisingjaws or strips movably connected at one oftheir ends and whereof one of said jaws is provided with a projectionadapted and arranged to engage with a complemental depression on theother 0 jaw, whereby accidental movement of the jaws in all directionsis prevented.

2. A hair-crimper comprising jaws or strips movably connected at one oftheir ends, one of said jaws being provided with an over- 5 hangingprojection or lip having a depression and the free end of another jawhaving a complemental projection adapted and ar- 10 having acomplemental projection adapted and arranged to engage with saiddepression, whereby accidental movement of the jaws in all directions isprevented.

In testimony whereof I have hereunto signed my name.

JAMES F. MARTIN.
